SEED-SOWER.

SPECIFICATION forming part of Letters Patent No. 416,127, dated November26, 1889.

' Application filed September 8, 1888. Serial No. 284,415. (No model.)

To all whom it nuty concern.-

Be it known that I, CARL W. SoRENsEN, of Racine, in the county'ofRacine, and in the State of WVisconsin, have invented certain new anduseful Improvements in Seecl-Sowers; and I do hereby declare that thefollowing is a full, clear, and exact description thereof.

My invention relates to seeds owers, and will be fully describedhereinafter.

In the drawings, Figure 1 is a plan View, in section, on line 1 1, Fig.3, of my invention. Fig. 2 is a section on line 2 2, Fig. 3, showing thedistributer in plan. Fig. 3 is a section on line 3 3, Fig. 1. Fig. 4 isa section on line 4 4, Fig. 5. Fig. 5 is an end view of the clutch. Fig.6 is a section on line 6 6, Fig. 1. Fig. 7 is a detail. Fig. 8 is asection on line 8 8, Fig. 1. Fig. 9 is a section on line 9 9, Fig. 1.Fig. 10 is a detail View showing the manner of securing the shelf whichsupports the seedsower to the end-board of a wagon.

A is the shelf that projects from the endboard B of a wagon, to which itis secured by brackets a, the vertical portion of each of which isbolted to the endboard, while its horizontal portion projects out underthe shelf and is formed with a flange b, that lies against the edge ofthe shelf and has lugs c, that overlap its edges, thus serving to strengthon it and prevent it from warping.

The shelf A is apertured at or near its center, and in one side of thisaperture is fixed a bearing (Z, having a hollow arm (1, by or throughwhich it is bolted to the table. The outer end of arm cl stands at rightangles to its greatest length, and an opening 01 therein leads throughthe arm to the interior of the bearing to afford a channel for conveyinga lubricant to the shaft 0, that has its upper bearing therein, andwhich carries the feedwheel D and distributor E.

F is a portion of the usual bevel-wheel of constructed, by the suddenstarting of the horses when the machine is at a standstill, or by anyjerking or unusual strain applied to the wheel or pinion when the deviceis in motion.

G is a disk that has an upturned flange e on its outer edge, and thisdisk is adjustably centered to the under side of an annulus H by aseries of lugs f on the under side of said annulus, the disk and annulusbeing loosely held together by clips f, that are screwed to the underside of the lugs f. The lugs f are formed with offsets f which supportthe body of the annulus out of contact with the shelf A, and the screwsg, that secure the annulus to the shelf, pass through its offsetportion. The base-ring h of the hopper is secured to the annulus by jaws7L, bolts 7L2, and thumbnuts h The disk G has an arm 5, that extends outfrom it toward the wagon, and a boss j on the outer end of this armrests on a perforated quadrant, upon which it is locked by a pin 70,that is projected loosely through boss j into the perforation thatregisters with pin it: when the disk is properly set to bring the centeropening of disk in proper position with relation to thedistributor-arms. On top of arm 't'is formed a guide-lug i, thatprojects up through a slot in a gage-plate L, which rests on the upperface of arm 2' and extends beneath the annulus H and into the feed-chantber M, and this plate may be drawn in or out to reduce or increase thearea of the dischargeopening m, which leads down through verticalguide-troughs m, that are secured to the under side of the disk.

The upper face of the plate .L is graduated or sealed for adjustment topositions for giving the proper area to the opening for the kind of seedto be sown.

The seed-chamber M is formed by a circular wall M, that is secured tothe disk G by bolts that pass through lugs n on its periphery, and aportion of this Wall M forms a gate 9 N, that is hinged at one end tothe disk, while its other end fits loosely between upright lugs or pins0 on the upper face of the disk, so that when the plate L is forced init will cause the gateto contract the seed-chamber as the outlet iscontracted. The guide-troughs are slightly inclined outward and projectdown between the inner end of the vertical flanges of thedistributer-arm and the hub of the distributer, and a segmental plate Pis secured to the under side of the shelf in such a position that thelower edge of its vertical portion will just clear the vertical flangesof the distributer. This plate serves as a guard to prevent the seedfrom being thrown or blown back toward the wagon.

A force-wheel D, of rubber, is fitted on the shaft 0 in theseed-chamber, and a plate S is fastened down on the upper edge of thewall of the seed-chamber, which plate prevents the seed from fallingdown through the opening m directly from the hopper.

The elasticity of the rubber of which the feed-wheel D is made issufficient to secure it against turning independently of the shaft 0under ordinary circumstances; but if a stone or nail or another foreignbody should get in the seed-chamber and clog the wheel the shaft willslip in its bearing in the wheel and revolve independently of it; or, ifthe obstruction is slight, it may suffice to merely bend the elasticfingers of the feed-wheel, and so permit said fingers to yield and clearit.

One member R of the clutch of the drivingshaft R consists of a sleeve,on which the sprocket-wheel T, that drives it, is loosely splined. A11annular groove T is formed on one end of sleeve R to receive the spannerof lever R while the other end is formed with lugs 1', that projectbetween similar lugs 0" on the member R, that is keyed to thedriving-shaft.

The gage-plate L is held in adjustment by a clamp 2' and set-bolt t andthe feed to the distributor is regulated to suit the kind of seed to besown by forcing the plate L in or out, so as to enlarge or contractopening m and seed-chamber, for as the plateL is drawn out it uncoversthe opening on, and, drawing gate N with it, enlarges the seed-chamber,and when it is thrust in it produces a contrary effect.

The throw of the seed is regulated by turning arm ito the right or left,and thus carrying the opening-m and guide-troughs to the right orleft,according to the direction of cast desired.

The Win gs E of the distributer, having vertical blades which terminateabout on a vertical line with the opening m in the disk G and the lowerend of the troughs m, depend nearly to the base-plate of the distributerE and in the circle of travel of the inner ends of the blades, theirlower ends being closed by a flange m that guides the seed out to thewings.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination, with a disk having a suitable seed-opening andforming the bottom of the hopper, of a seed-chamber formed by asemicircular wall secured to the bottom of the disk and a gate hinged tosaid disk, and a sliding gage-plate connected to said gate and adaptedat once to contract or enlarge both the seed-opening and theseed-chamber, substantially as described.

2. The combination, with the disk forming the bottom of the hopper andhaving a seedopening on one side of its center, of a seedchamberarranged on said disk, the usual distributer-shaft, a plate covering theseedchamber over the seed-opening, and a feedwheel carried by thedistributor-shaft and adapted to yield when opposed by extraordinarypressure to permit the shaft to revolve independently of it,substantially as described. 3. The combination, with the seed-chamberand its outlet-opening, of an approximately vertical trough extendingdown from the seedopening and having its lower end closed by ahorizontal guiding-flange, and a distributer the blades of which travelin a circle about the lower portion of the trough, substantially asdescribed.

a. The combination, with the sower and supporting-shelf, of a bearingfor the distributer-shaft having a hollow arm that extends out to oneside of the shelf, substantially as described.

5. The combination, with the disk and seed chamber, of the guide-troughsand distributer and a segmental plate depending from the shelf andoverhanging the path of the inner end of the distributer-blades and withthe troughs forming a channel from the opening in the shelf to thedistributer, substantially as described.

6. In a seed-sower, the combination, with the distributer-shaft and itsbevel-pinion, of a driving-shaft and a bevel-wheel carried thereby, aclutch mechanism, and a sprocketwheel splined on one member of saidclutch mechanism and adapted to adjust itself there- I 011 to align withthe sprocket of the wagonhub, substantially as described.

'7. The combination, with the seed-chamber and its outlet-opening, of adistributor having a vertical shaft and radially-disposed verticalblades'whose inner ends terminate at some distance from said shaft, soas to leave an annular channel around the latter, and an approximatelyvertical trough extending down from the said seed-opening into saidannular channel, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, atRacine, in the county of Racine and State of Wisconsin, in the presenceof two witnesses.
